Abstract
A method and device for scheduling signaling and data packets during Push-to-talk (PTT) sessions. An exemplary embodiment of the invention includes scheduling data packets and signaling packets during a push-to-talk session by detecting periods of silence in the talk-burst, inserting signaling packets between the data packets in the periods of silence in the talk-burst; and transmitting the signaling data packet along with the data packets. In another aspect of the invention, downlink signaling packets are suspended during the push-to-talk session.
